The use of designated resources and power control enhances reliability and reduces the likelihood of transmission failures. This approach is particularly useful in dense network environments where multiple devices may attempt to access system information simultaneously.

Claim 27

Original Legal Text

27. A non-transitory computer-readable medium having program code recorded thereon, comprising: program code for causing a computer to generate a reference sequence correlating to a timing of a zone node defining a zone along with one or more other zone nodes; program code for causing the computer to assemble a payload including a format for a system information transmission request for a user equipment (UE), wherein the payload includes at least a resource allocation for the UE to transmit the system information transmission request, and the system information transmission request is a request to transmit a system information block (SIB); program code for causing the computer to encode the payload; and program code for causing the computer to transmit a synchronization channel using a single frequency network (SFN) across the zone, wherein the synchronization channel includes the reference sequence and the encoded payload.

Plain English Translation

This invention relates to wireless communication systems, specifically methods for transmitting system information in a synchronized manner across a defined zone. The problem addressed is the efficient and reliable delivery of system information, such as system information blocks (SIBs), to user equipment (UE) in a network where multiple nodes collaborate to form a synchronized transmission area. The system involves generating a reference sequence that correlates with the timing of a zone node and other nodes defining the zone. This sequence helps synchronize transmissions across the zone. A payload is assembled, containing a format for a system information transmission request for a UE. The payload includes resource allocation details for the UE to send the request, specifically for transmitting a SIB. The payload is then encoded and transmitted via a synchronization channel using a single frequency network (SFN) approach across the zone. The synchronization channel carries both the reference sequence and the encoded payload, ensuring coordinated and synchronized delivery of system information to UEs within the zone. This method improves reliability and efficiency in system information dissemination in wireless networks.

Claim 28

Original Legal Text

28. A non-transitory computer-readable medium having program code recorded thereon, comprising: program code for causing a computer to receive a synchronization channel over a single frequency network (SFN) at a user equipment (UE), wherein the synchronization channel includes a reference sequence and an encoded payload; program code for causing the computer to synchronize timing at the UE using the reference sequence; program code for causing the computer to decode the encoded payload to obtain at least a format for a system information transmission request and a resource allocation for the system information transmission request, wherein the system information transmission request is a request to transmit a system information block (SIB); and program code for causing the computer to transmit the system information transmission request to a zone node based on information obtained in the synchronization channel, wherein the system information transmission request is transmitted according to the resource allocation.

Plain English Translation

This invention relates to wireless communication systems, specifically methods for synchronizing user equipment (UE) and requesting system information in a single frequency network (SFN). The problem addressed is efficient synchronization and system information acquisition in SFN environments, where multiple nodes transmit the same signal to improve coverage and capacity. The invention provides a non-transitory computer-readable medium containing program code for a UE to receive a synchronization channel over an SFN. The synchronization channel includes a reference sequence for timing synchronization and an encoded payload containing system information transmission request details. The UE uses the reference sequence to synchronize its timing. The encoded payload is decoded to extract a format for a system information block (SIB) request and a resource allocation for transmitting this request. The UE then sends the SIB request to a zone node using the allocated resources, ensuring efficient and coordinated system information acquisition in the SFN. This approach optimizes synchronization and system information handling by embedding request formats and resource allocations directly in the synchronization channel, reducing signaling overhead and improving reliability in SFN deployments.

Claim 29

Original Legal Text

29. An apparatus configured for wireless communication, the apparatus comprising: at least one processor; and a memory coupled to the at least one processor, wherein the at least one processor is configured: to generate a reference sequence correlating to a timing of a zone node defining a zone along with one or more other zone nodes; to assemble a payload including a format for a system information transmission request for a user equipment (UE), wherein the payload includes at least a resource allocation for the UE to transmit the system information transmission request, and the system information transmission request is a request to transmit a system information block (SIB); to encode the payload; and to transmit a synchronization channel using a single frequency network (SFN) across the zone, wherein the synchronization channel includes the reference sequence and the encoded payload.

Plain English Translation

This invention relates to wireless communication systems, specifically addressing the need for efficient synchronization and system information transmission in networks with multiple zone nodes defining a communication zone. The apparatus includes at least one processor and a memory, where the processor generates a reference sequence that correlates to the timing of a zone node and other nodes within the zone. This reference sequence helps synchronize communication across the zone. The processor also assembles a payload containing a format for a system information transmission request for user equipment (UE). The payload includes resource allocation details for the UE to transmit a request for a system information block (SIB), which is a critical component for UE operation in the network. The payload is encoded and transmitted via a synchronization channel using a single frequency network (SFN) approach, ensuring consistent delivery across the zone. The synchronization channel carries both the reference sequence and the encoded payload, enabling UEs to synchronize with the network and request necessary system information efficiently. This method improves coordination between zone nodes and enhances UE access to essential network data.
